Abstract：The work to define spatial relationship among urban economic influence regions is a quite difficult issue, but an important job to urban geography and urban planning. In the previous research, it is often based on methods in mathematical statistics to quantify the influence power of cities, and then cities are classified based on it, but this strategy doesn't consider the spatial competitive relation between cities. For delimitating urban affected coverage, spatial interaction model is generally employed to define the potential equilibrium boundary of attraction between two towns. However, if there are many cities, this approach would face many obstacles. This paper presents a new method for it. Firstly, Voronoi diagram is used to delimitate urban spatial influence regions, then according to the relationship of attribute value of a Voronoi polygon' centroid and ones of its nearest neighbors, the hierarchy of cities in a region is ordered.
